Selling of factually incorrect exam packs

The service provide, Luciano School of Law and Social Sciences aggressively advertises and sells solutions of previous exams that students can buy in order to help them prep for current exams. They advertise this service by SMS to students who are in their current curriculum at leading universities. The problem is that once paid, one receives solutions that appear to have been done by someone who doesn't understand the questions, and are factually incorrect on almost every second line. I have appealed to the service provider, pointing out the amount of faults in what is suppose to be 100% correct in order to assist students in their preparation. The college director, Rungano Luciano, at first didn't respond, and when he sent out another advertising email I called him on it and said I would hold him accountable. He simply responded: \good luck". This is very poor form from an institution that is meant to aid students in their studies"
